CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N0.339,568, dated April 6,1886.

Application tiled Februar-54, 1886. Serial No. 100,794.

vertical section thereof. Fig. 3 represent-s a front view thereof,partly broken away; and

Fig. 4 represents a horizontal section of a portion iu line a", Fig. 3.

Similar letters of reference indicate corresponding parts in the severalfigures.

Our invention consist-s of an automatic carcoupling possessing novelfeatures, aswill be hereinafter fully set forth.

Referring to the drawings, A represents a draw-head, which, excepting asfar as our iuvention relates thereto, is of usual form.

B represents a coupling-pin, which is connected with the forward end ofthe spring-bar G, the latter having its rear end secured to thedraw-head, whereby the pin is caused to be lowered and retained inposition when the 3o ears are coupled.

In lieu of the spring-bar C we may employ a hinged bar, C, the saulefalling by gravity, and having the pin D pivoted to it.

Mounted on the draw-head is a block, D, so disposed that when rotated itbears against the bar C and raises thesamaand consequently thecoupling-pin.

Vithin the drawhead is a sliding head, E, which is connected with auarm, F, the latter 4o being` pivoted to the lower end ofthe block D,whereby, when the coupling-link G enters the draw-head, it strikes thehead and forces the same rearward, thus causing the dropping of the barC.

Mounted on the draw-head is alink-holder, H, which is hook shape androtates within the draw-head, so as to bear against the inner end of thecoupling-link and hold the saine, whereby the link is in condition forcoupling.`

(No model.)

In order to retain the holder H in operative position against the link,the saine has connected with it a crank arm or lever, J, whose end isadapted to drop into a recess, K ,on the side of the draWhead.

L represent-s a rod, which extends horizontally and longitudinally alongthe side of the drawdiead and fitted in openings therein, the rear endsof said rod having a shoulder, M, which, when the lever J is thrown up,as in the right side of Fig. 2, is adapted to bear against said lever.The front end of said lever is adapted to project infront of thedrawhead, so as to be struck by the opposite drawhead.

ln order to couple the cars the coupling-pin 65 of one of the draw-headsis raised by operating the block D thereof, said block having aconnected lever, D, for conveniently rotating the block. Thecoupling-link is now inserted into the draw-head and the pin dropped,whereby the latter enters the link. The holder is then swung upwardlyand forwardly, so as to engage with the inner end of the cou pling-linkand hold the link rigidly, projecting forwardly from the draw-head. Theeoupling- 7 5 pin of the other dran/'head is raised by its block D, theposition of parts being shown in Fig. 2. As the ears approach, thecouplinglink entering the draw-head bears against the head E and forcesthe saine inwardly or rear- 8o yrelease the bar C, the latter thendropping,the

pin then entering the link, whereby the cars are coupled, the samehaving been effected in an automatic manner, and consequently with 8 5safety to the train-hands. As soon as the draw-head strikes the rod Lthe lever J is forced from the recess K and then drops, whereby theholder H rotates and clears the end of the link, leaving the latter freeto play in the draw-heads.

The cars can be readily uneoupled by raising either of the bars Cthrough the operation of the proper block D.

Having thus described ourinvention, what we claim as new, and desire tosecure by Letters Patent, is-

l.. The drawhead A, having the side recess,

K, substantially as described, in combination with the rotatable holderH, link G, and pivoted bar J, substantially as described.

2. The draw-head A, having recess K, in combination with the link G, theholder H, the pivoted bar J, and reciprocating rod L, having the head M,substantially as and for the purpose set forth.

3. Aliuk-holder consisting of arotary piece adapted to bear against theend of the link, an operating-lever attached to said piece, and a rodwhich is operated by contact With the opposite draw-head and moves saidrod,and corr sequently the link-holder, thus releasing the link,substantially as described.

4. The draw-head Ahaving recess K, in combination with link G, the pinB, pvotally secured to the bar G, the block D, the sliding head with armF, pivotally secured to said block D, the pvoted bar J, and sliding rodL, with shoulder M, all arranged, combined, and Operated substantiallyas and for the purpose set forth.
